The manufacturer of a sealant barrier says its product is well suited for sealing transformer pad openings. American Polywater Corporation’s new InstaGrout Sealant Barrier makes sealing transformer pad openings simple. The company says the sealant can help prevent outages and service disruptions by creating a resilient and impermeable barrier that keeps out moisture and stops rodents, snakes, and insects from burrowing up through earthen gaps into the pad enclosure.
The product’s polymer matrix composition makes it easy to mix on site and requires no water. Field crews combine the pre-measured components and shake or stir for 30 seconds. The sealant is then poured into the transformer pad opening. The self-leveling mixture spreads out and expands evenly throughout the pad opening and around conduit stub-ups. The only site preparation required is to plug any gaps or holes inside the opening that could allow product to flow outside the pad opening. InstaGrout adheres to fiberglass, polymer concrete, and concrete pads. It tolerates environmental extremes and effectively seals uneven ground. It will not settle, crack, or cave in like concrete can when performing service work or transformer change-outs.
